About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75S
The AirTAC SAIJ32X270-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 195 to 270 mm, allowing you to dial back the nominal 270 mm stroke by up to 75 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty applications perfectly.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid connections use PT tapered ports sized at G1/8.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75S Is Used
Variable End-Stop Tuning
Fine-tune the retract end position within the 195-270 mm window during machine setup to accommodate changing product sizes without external physical stops.
Product Changeover
Rapidly adjust the effective stroke on automated lines when switching between part lengths, using the rear screw to set the exact travel distance.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in light assembly machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75S the Right Cylinder?
Choose this 32 mm bore model when you need precise end-position tuning without swapping cylinders or adding external stops; if you need less force, step down is not an option here, but stepping up to a 40 mm bore yields 628 N push force at 0.5 MPa. Because the 270 mm stroke exceeds 300 mm is false here, but for any long unsupported travel, an external guide is still recommended to manage side load.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, select an SAIL or BSAI cylinder. This SAIJ32X270-75-S is dimensionally interchangeable with ISO 15552 cylinders, featuring a 270 mm stroke, 75 mm adjustment range, PT G1/8 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a -S magnet.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 75 mm, creating a usable stroke window of 195 to 270 mm. This allows fine-tuning of the end position at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
